Lane keeping system for autonomous vehicle during camera drop-outs
An environmental sensing system relating to vehicle lane position includes first and second sensors respectively configured to provide first and second signals indicative of a vehicle lane position. A steering system achieves a desired lane position in response to a command from a controller to keep the vehicle in its lane, for example, during autonomous control of the vehicle. The controller uses the first signal if the first sensor provides a desired lane marker confidence. The controller switches to the second sensor and uses the second signal if the first sensor cannot provide the desired lane marker confidence and the second sensor can provide the desired lane marker confidence.
Irrigation system having terrain compensation
A control system for an irrigation system is disclosed that is configured to prevent a substantial positional change of the irrigation system while the system is traversing a substantially non-flat terrain, or surface. In an implementation, an irrigation system includes multiple interconnected spans that are supported by multiple tower structures. Each tower structure includes a drive unit for driving a tower structure at a selected speed. The irrigation system also includes a position-determining module configured to determine an actual position of the main section assembly. The irrigation system also includes a control device configured to determine an actual position of the main section assembly, compare the actual position with a desired position of the main section assembly, and to determine that the main section assembly is traversing a substantially non-flat surface.

Rotation detection apparatus, rotation angle detection apparatus, and electric power steering system
A rotation detection apparatus, a rotation angle detection apparatus are provided which allow appropriate detection of an abnormality in a portion that detects rotation of a rotating shaft. A first arithmetic circuit calculates a rotating direction and a number of rotations of the rotating shaft based on a change in a combination of positivity and negativity of a first electric signal (first sine signal) and a third electric signal (first cosine signal). A second arithmetic circuit calculates a rotating direction and a number of rotations of the rotating shaft based on a change in a combination of positivity and negativity of a second electric signal (second sine signal) and a fourth electric signal (second cosine signal). An abnormality determination circuit determines whether each of the first and second arithmetic circuits and is abnormal based on the two rotating directions and calculated by the first and second arithmetic circuits respectively.
